Docs/ABI/damon: document update_tuned_intervals state command

Browse Source 
The 'update_tuned_intervals' command of the 'state' file, added in commit
1077605396 ("mm/damon/sysfs: implement a command to update auto-tuned
monitoring intervals"), is described in usage.rst but missing from the
canonical ABI document.  Add it.
